我尝试使用 Windows azure 移动服务作为数据库来创建登录注册页面。我在注册为用户时遇到问题，我可以使用 2 个相同的用户名进行注册。是否可以使用户名唯一，所以我不会有重复的用户名。我还想知道如何取回 WAMS 中的数据，以便我能够检查用户名和密码以使登录部分正常工作。仅供参考 btn1 用于登录，btn2 用于注册。请帮我看看该怎么做。谢谢。

You should use a server script when you insert a new value into your table to check whether that name already exists in the table. For an example, check this tutorial. Also, please don't store the plain password in your table, but use that same insert script to hash the password and store the hash.

Josh Twist has a good blog post showing how to build custom identity with Mobile Services.

Thanks, Yavor
